Hi,
I am optimizing my strategy on calgo (ctrader) with tick data precision from server and with 10,000 deposit I am getting results like 13 billion profit with 10k deposit.
How reliable is such backtesting, do you think real results could be at least close to it?

I got no experience on cAlgo, but whats the avg trade duration?
if i were you id test it on a small account and see what happens..
worst case you loose a few hundred, but sure as hell worth the risk..

I think it all depends on the strategy, if this is a scalper, then it will be highly dependent on the spread and execution rate which can jeopardize the real results greatly.
What time span is that? 5 years?
Results look really good, but too good to be true for live testing, the market is always working against you, but then again, with 8000+ trades, it is highly possible to have good returns, but the DD is what I would be leary of. So low that it generally implies a scalper, which I have never seen a scalper that actually makes it without huge DD in real life. I don't trust scalpers, too many factors to make them profitable and reliable

The question is if this strategy results are so marvelous
How reliable is backtesting of other strategies with 'normal' results.
I do trade ctrader live on 10k account so I need to know if I can rely a bit on BT

Backtesting is a crap thing.
CTrader or MT4, I guess it the same crap thing. even with 99% Quality, backetesting means nothing.
I realizaed this by myself when I did perform some testings.
When you realize that you can get very different result from different brokers by using the same EA, you say 'WTF'
Then when you backtest the day (current day) while you had your EA on live the same day... and realize that backtesting doesn't provide same trades... Then you understand backtesting is so rubbish.
The real use of backtesting, it to make sure you have well coded your strategy and EA opens/closes when it supposed to do it.
You test that EA behaves well as expected. That's the only point of backtesting.
Some scarmers then used backtesting to show unneatable performance... and then everybody started on the same way.

@CrazyTrader Some EA's are more reliable when it comes to backtesting then others, there are many factors..
If you know what your doing your backtest and live trading can be damn near exact within a few pips max..
If your backtesting isnt matching your live trading you really gotta ask yourself why, as its not the backtest its your algorithm especially if its a 99% tick data..
Main reasons peoples backtest dont match live trading:
- Their tp/sl is not more then 10x the avg spread..
- They curve fit periods without out of sample testing..
- EA has too many variables that allows it too much freedom on backtest makes it more of a curve fit..
- Trailing stops are used as takeprofit without taking into consideration spread widening on volatile markets..
- Pending stops are used, these create alot of slippage..
- Trade duration is too fast for retail trading..

@CrazyTrader
Perhaps if you spend more time backtesting you could have at least one profitable account. You dont. Point.

I would say it depends a lot of the EA of whether or not backtesting will yield results close to what the Real Testing will yield. In the case of Scalpers, I never trust them in backtests for the reasons CrazyTrader mentioned. When you deal with only a few pips being won or lost, the backtest is very faulty because the spread can easily eat the winning trade in those cases.
The Strategy Tester is best for EAs that win 10+ pips but it still is no where near perfect. Vontogr is correct that you then need to forward test and eventually live test it on a real account (at lowest risk settings) to really see if it profitable.
A lot of work, if the backtest fails, then that is an early sign that an EA is no good, but a good backtest is no indication that it will profit in real world trading.
